Windows 10: Computer freezing/crashing shortly after startup

A couple of days ago my PC randomly froze during normal use and required a hard reboot. Ever since then it has been freezing or crashing about 1-3 minutes after startup. Everything functions completely normally up to the point of the freeze/crash. This happens during regular use, on the login screen, in the blue Windows recovery screen, safe mode, clean boot, sometimes even during the startup while the Gigabyte logo is still displaying. The only place where it does not happen is in the BIOS menu, which I have left on for several hours without a freeze or crash, so I don't think it's a Mobo iss

Windows 10 freezes shortly after logging in

Jan,

Thank you for the help. I went through all the suggestions you offered. None of the scans returned any errors. I also went through the steps on the page you linked to.

In addition, I also ran "mdsched.exe" and a disk check, which also returned no errors.

Unfortunately, the problem has not gone away. My computer freezes shortly after logging in.

Do you have any other suggestions for diagnostics I might be able to use?

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

ive watch my temps and both the cpu and gpu are within normal ranges. when it freezes it simply freezes the image and stops the sound. i must reboot to get back to windows.
